What equipment would you buy if you were me?

My apologies in advance if this is a reporst, I searched the site but didn't find the exact information.

Basically, I'm looking to purchase a riding 0-turn lawmower which can be a snowplower in the winter. What makes/models would you suggest? The chap in the home depot store said that it's basically an add on feature equipment which you can get for pretty much any ride on lawnmower. Is this correct? What is the name of this equipment?

I need a residential unit, 48"-52" blade, zero-point turn and something that can make it plow snow in the winter. In terms of brands I'm considering either John Deere or Cub Cadet. The return on investment i'll be getting is good and price is really not that much of an issue.

I'll dig deeper into the links and info you have provided first thing tomorrow morning. If anyone has any more suggestions, please don't consider it a big chore to post it up.
